Method for dyeing and finishing bamboo fiber fabric

Abstract

The invention provides a method for dyeing and finishing a bamboo fiber fabric, and relates to an improvement of a method for treating a fabric, in particular to an improvement of the method for dyeing and finishing the bamboo fiber fabric. The method provided by the invention adopts a dyeing and finishing process comprising the steps of enzyme desizing, singeing, oxygen bleaching, unhairing enzyme finishing, dyeing, and after finishing. The step of dyeing adopts a vat dye, presetting is carried out before dyeing at 140-150 DEG C to ensure that a cloth cover is flat before dyeing, and drying fixation is carried out after dye dipping treatment during the presetting before dyeing; and the dye for dyeing contains X%(o.w.f) anhydrous sodium sulphate of Yg/L, a substitution alkali M-231P:2-2.5 g/L, and a cotton leveling agent M-230K of 1-2 g/L, the temperature and time are 60 DEG C and 30-60 min, the bath ratio is 1:(6-10), and the M-231P is a substituent alkaline agent for dyeing of a reactive dye. The method provided by the invention enables the bamboo fiber fabric to keep water absorption after use, thereby ensuring a use hand feeling of the bamboo fiber fabric and the service life of the bamboo fiber fabric. Through adoption of the method, process flows are simplified and energy sources are saved. The unhairing enzyme finishing after oxygen bleaching improves the chromaticity and glossiness of a product, and normal temperature pressure jig dyeing is adopted to avoid the condition that the tension of a textile is too large, and effectively avoid phenomena of broken ends, scratches and the like, thereby reliably ensuring the quality of a product.

Description

technical field [0001] The invention relates to an improvement of a fabric treatment method, in particular to an improvement of a bamboo fiber fabric dyeing and finishing method. Background technique [0002] Bamboo fiber fabric is a new type of fabric made from bamboo as raw material, made of bamboo fiber by special technology, and then woven. Features: smooth, soft and warm, antibacterial and antibacterial, moisture-absorbing and breathable, green and environmentally friendly, anti-ultraviolet, natural health care, comfortable and beautiful, etc. Experts pointed out that bamboo fiber is a real natural environment-friendly green fiber. Bamboo fiber textiles are favored by consumers because they fully replicate the inherent characteristics of bamboo fiber, and the demand for products is increasing year by year.

AI Technical Summary

Problems solved by technology

[0003] Compared with pure cotton towels, bamboo fiber towels have a shorter service life. After a period of use, the cotton loops on bamboo fiber towels are easy to fall off, making the towels lose their softness and warmth before and become dry and hard.

Softener should be used before use. Compared with pure cotton fabrics, the air permeability and instant water absorption of bamboo fiber products gradually decrease after use, and the long-term use effect is not as good as that of pure cotton fabrics.
